Email security is an ever-growing concern, especially amongst financial institutions. Phishing and spoofing are as old as email. The occurrences will continue to grow without the industry coming together to fix the problem.

Until recently, many people hadn't even heard of any type of sender authentication such as YAHOO DomainKeys. These sender identification protocols are a vital step to ensure email is an effective business tool. They help reduce many email security threats including phishing, spoofing, viruses and spam. One day we will be able to rely on email as much as we do snail mail, but at 1% of the cost and 2.6e-4 of the delivery time.
